Hi All,

Could you guys please share the QA’s/procedures that you perform following an ACO calibration?

Thanks,

Hi Ash,

we have modified a calibration plate with 5 metal-sphere fiducials (diameter 1,5mm, stainless steel, one positioned at the center and the others along the two axes). We perform a system calibration after aligning this calibration plate carefully to the x-ray isocenter.

BR,

Marcus

Hi Marcus,

Thank you for your message. Using metal BBs—that’s a great idea. I am just curious if we should include an off-isocenter test (e.g., at ±10cm)?

Thanks,

Ash
